It should be understood that in the embodiment of the present application, the terminal device may perform signal measurement before S210. For example, the terminal device may measure at least one return amount of the N signals. Further, in S220, the terminal device Signal selection may be performed based on the measurement result of the target return amount; or the terminal device may perform signal measurement after S210, for example, the terminal device may determine the target return amount in the at least one return amount, and then select the N signals The target return amount is measured, and further in S220, signal selection is performed based on the measurement result of the target return amount, which is not limited in the embodiment of the present application.

In a specific implementation, if the K signals are CSI-RS, the identification information of the K signals may be CSI-RS resource index information; or if the K signals are SSB Signal, the identification information of the K signals may be SSB index information (SSB index).

In other words, the target return amount may include only measurement results on L1-RSRP, L1-SINR, or L1-RSRQ, or it may also include information on the returned signal, for example, information related to reference signal resource identification (such as CSI- RS resource index or SSB index).

Optionally, in the embodiment of the present application, the terminal device may only report the target return amount information to the network device, or may also report other return amount information to the network device, for example, if the target return amount Including the measurement result of L1-SINR, the terminal device can also report the measurement result of L1-RSRQ or the measurement result of L1-RSRP of the K signals to the network device.

For the convenience of description and explanation, the description of the return amount is L1-RSRP, L1-SINR, or L1-RSRQ, and the omission of other information that may be included in the return amount, for example, the information of the returned signal, but this does not mean that This information is not included in the return.

In the following, with reference to specific embodiments, the signal return method of the embodiments of the present application will be described in detail.

Embodiment 1: At least one return amount includes only the first return amount, that is, the network device configuration independently measures the first return amount.

Optionally, the first return amount may be L1-RSRP, L1-SINR, or L1-RSRQ, or may also be other signal quality information, which is not limited in this embodiment of the present application.

The first return amount may be configured through the first measurement configuration information, that is, the network device may configure only one return amount through the first measurement configuration information, and the terminal device may be based on the measurement result of the one return amount of the N signals , Select K signals to report, for example, the measurement result of the first return amount of the K signals.

Optionally, the network device can also configure the second return amount through the second measurement configuration information, and the terminal device can perform signal selection and return based on the measurement result of the second return amount of the N signals.

In other words, the network device can configure the corresponding return amount through independent measurement configuration information, and the terminal device can perform independent measurement, signal selection, and return according to different measurement configuration information. That is, each measurement configuration information corresponds to independent signal measurement, signal selection, and return actions.

For example, if the first return amount configured by the first measurement configuration information is L1-SINR and the first return amount configured by the second measurement configuration information is L1-RSRQ, then the terminal device can measure the L1-SINR of the N signals As a result, K1 signals are selected, and the L1-SINR measurement results of the K1 signals are reported to the network device, and based on the L1-RSRQ measurement results of the N signals, K2 signals are selected and reported to the network device Measurement results of L1-RSRQ of the K2 signals, where the K1 and K2 are positive integers, and the K1 and K2 may be the same or different.

Here, the measurement results of the target returns can be L1-RSRP, L1-SINR, or L1- RSRQ measurement results, or may be L1-RSRP, L1-SINR or L1-RSRQ measurement results difference (for example, relative to a specific measurement result difference, or the difference between measurement results, etc.), or The quantized value of the measurement result of L1-RSRP, L1-SINR or L1-RSRQ, etc., the embodiment of the present application does not limit the return form of the measurement result.

Optionally, in some embodiments, when the network device is configured with only one return amount, the terminal device may select signals based only on the measurement result of the one return amount, or may select other return amounts to assist in signal selection, For example, if the return amount configured by the network device is L1-SINR, the terminal device can autonomously choose to measure L1-RSRQ to assist signal selection through the measurement result of L1-RSRQ.

In other words, if the return amount configured by the network device is the first return amount, the terminal device may choose to measure the second return amount of the N signals, and then measure the first return amount of the N signals As a result, combining the measurement results of the second returns of the N signals to perform signal selection helps to improve the reliability of the quality of the selected signal and improve the system performance.

In this case, since the network device does not know which measurement result of the return amount the terminal device reports, the terminal device needs to notify the network device which measurement amount corresponds to the measurement result.

In the following embodiment 2-2 to embodiment 2-4, the terminal device may perform signal selection and return based on the preferred return amount and the auxiliary return amount. It should be understood that the preferred return amount and the auxiliary return amount may be indicated by a network device, or preset on the terminal device, or selected by the terminal device. For example, the preferred return amount may be L1-RSRP, and the auxiliary return amount may be other return amounts than L1-RSRP, for example, L1-SINR or L1-RSRQ; or vice versa.

Optionally, in some embodiments, the terminal device may also determine which of the first return amount and the second return amount is preferred according to the position of the return amount in the measurement configuration information As for the amount of return, which is the auxiliary amount of return, for example, it can be determined that the return amount at the top position in the measurement configuration information is the preferred return amount, or the return amount at the rear position is the preferred return amount.

Optionally, the terminal device may also determine the preferred return amount and the auxiliary return amount according to the types of the first return amount and the second return amount, for example, L1-RSRP is the first type, The other types of returns are the second type, and it can be determined that the first type of return is the preferred return, or the second type of return is the preferred return.

Embodiment 2-2. The terminal device performs signal selection according to the measurement result of the preferred return amount. When the measurement results of the two preferred return amounts are the same, it is determined which signal has the better quality according to the measurement result of the auxiliary return amount.

Optionally, the threshold may be agreed upon, or configured by the network, or preset on the terminal device.

In this case, it can be considered that the signal qualities of the N signals are not significantly different, or that the signal qualities of the N signals are similar, therefore, the signal selection is performed based on the measurement result of the preferred return amount, and the determined K signals are not necessarily It is the optimal K signals. At this time, the selection of signals in combination with the measurement results of other returns helps to improve the reliability of signal selection and thus improve the system performance.
